Abstract: The present invention provides, in a first embodiment, a battery lifter including: at least one arm having a first end and a second end; at least one leg extending from an end of the at least one arm; and opposed means for grasping a battery, each means for grasping including a hook formed at an end of the at least one leg opposite that of the at least one arm, and an inwardly directed toe disposed on the end of the hook opposite the at least one leg for engaging the battery. In an alternative arrangement, the present invention provides a battery lifter including: a first element and a second element, the first and second elements each including a plate, an extension extending laterally from an end of the plate, and a downwardly depending leg extending from an end of the extension opposite the plate; the leg of each of the elements including a hook for engaging battery; and means for adjusting the position of the second element relative to the first element.

Abstract: A specially configured wrench is fitted to the fork structure of the rear wheel of a motorcycle to transmit rotational torque to the axle and move the rear wheel axle and sprocket to adjust and accurately set the tension in the drive belt of the motorcycle to a desired level. Further, a method is disclosed for reducing slack, changing, and/or setting a desired tension in the flexible power transmission mechanism of a motorcycle, the mechanism exemplified by a chain or drive belt having upper and lower reaches wrapped about respective of a rotatable forward motor drive sprocket and a rotatable rear wheel drive sprocket and used in cooperation with a fork structure for mounting the rear wheel and a cam-operated structure for repositioning the rear sprocket and associated axle.

Abstract: A foot operated gear-shift assembly, gear shift conversion kit, and method for converting the shifting gears of a conventional motorcycle, all-terrain vehicle, and like vehicle wherein the heel and toe shift elements of the conventional rocker-arm gear shift assembly are separated and pivot about separate pivot axes.
